I want to upload one image to server using http post method.
the requirement is like in the body data should be attached as byte stream.
My code
[request setURL:[NSURL URLWithString:url-string]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"%#\"\r\n",#"images.jpg",#"images"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:data]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
but i am getting 404 error in status code.
is byte stream is same as NSData ?
if not then how to send byte stream data to server using NSURLConnection ?
Thanks in advance.

I am new IOS developer and I am facing a headache issue regarding to use multipart for uploading file and some text, i have tried a lot on here
The status code always return 400. I tired to test my web service with another way, such as build Rest client by HttpComponent API, using RestEASY client and both of them worked successfully, how funny!
I am using Xcode 6.1.1, my source code:
-(void)uploadPhoto {
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"http://localhost/my-rest-service"]];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:60];
[request setHTTPMethod:#"POST"];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:#"avatar_temp"], 1.0);
NSString *boundary = #"12345-6789-abc"; //
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
[body appendData:[[NSString stringWithFormat:#"%#--", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=%#\r\n\r\n", #"type"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", #"HELLO"] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the request
[request setHTTPBody:body];
// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if(data.length > 0){
//success
NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"[String] %#", str);
}
}];
}
Any suggestions will help my investigation
Thanks

You forgot to add imageData so add:
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
A full working example:
[request setHTTPMethod:#"POST"];
NSData *imageData = UIImageJPEGRepresentation(imageToSave,0.9); //change imageToSave with your own UIImage defined
NSString *filenames = #"first field";
NSString *token = #"second field";
NSString *boundary = #"---------------------------14738723651466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
////+++ first form field for post -> for example a field called filenames see NSString above
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];
////--- the second field for form post-> we named token see above NSString
////+++
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
////---
////+++ the file used to upload /post
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"ceva.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

// setting the body of the post to the reqeust
[request setHTTPBody:body]; // now lets make the connection to the web
Now all the you want to make is check your php code on server side.
NSString *filenames = [NSString stringWithFormat:#"front_img"];
NSString *urlString = #"http://ccccc.com/upfile.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"filenames1\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames1 dataUsingEncoding:NSUTF8StringEncoding]];
/*Sending First Image start here*/
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#.jpg\"\r\n", filenames]] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData1]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
/*Sending First Image ends here*/
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#",returnString);
A typical upload http body will look like:
--BOUNDARY_TEXT
Content-Type/Content-Disposition info key values
Base64 encoded file data ...
--BOUNDARY_TEXT
Content-Type/Content-Disposition info key values
Base64 encode file data.
--BOUNDARY_TEXT
You've done the first one, just continue append files according to the format seperatored by the BOUNDARY.
Hi I am working on an iOS app, from this there is a http post method for signup. This method is working perfectly fine with a dedicated server. But fails with a shared server.
There is no fail report in HTTP posting delegates (NSURLConnection), however the "didfinish" delegate is being called too. But the problem is no data is arrived in server side, we are posting plenty of details with an image - but nothing reached at server side.
In android same posting with same server is working fine without an issue.
What could be the reason. Please help me to fix this.
Here is the code for posting.
-(void)postMethod{
NSString *urlString =#"http://sharedserverurl.com";
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//Sending user_name
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"username\"\r\n\r\n%#", user_name.text] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//Sending user_id
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"user_id\"\r\n\r\n%#", user_id.text] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//Sending userImage
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"image\"; filename=\"userimage.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:file]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (conn) {
webData = [NSMutableData data];
}
}
I want to upload one image to server using http post method.
the requirement is like in the body data should be attached as byte stream.
I converted image to NSData and attached that data to body of NSUrlrequest.
but i am getting 404 in status code of response.
NSMutableData *body = [NSMutableData data];
[body appendData:[NSData dataWithData:UIImageData]];
[request setHTTPBody:body];
but i am getting 404 error in status code.
is byte stream is same as NSData ?
if not then how to send byte stream data to server using NSURLConnection ?
Thanks in advance.
What about the URL you're using to send the image to?
A 404 error code translates to Not Found (http://en.wikipedia.org/wiki/HTTP_404), so the first step should be making sure yore using a valid URL.
Try to make the upload that way:
NSData *yourData = //load your data here;
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:UPLOAD_URL]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"%#\"\r\n", UPLOAD_FILE, UPLOAD_FILE] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:yourData]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
[connection start];
I have a simple question- I'm currently writing a specific part in my app related to sending data to server.
I tried to send text, succeeded. Sent image, succeeded.
What I'm trying to do now is to send them both within one POST request.
I figured out that I need to use something that is called multipart/form-data and boundaries, but I haven't found anymore info about it.
So how can I send both text and image in one, simple POST request? And how can I check for errors during upload, afterwards etc.?
Thanks!
Reference code I've written but sending 0 bytes of info:
NSData *imageData = UIImageJPEGRepresentation(sendImage, 1.0);
// setting up the request object now
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://posttestserver.com/post.php?dir=something"]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------54737809831466490885746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"rn--%#rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Disposition: form-data; name=\"userfile\"; filename=\"reportingImage.jpg\"rn" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-streamrnrn" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"rn--%#--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: text/xml" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[[alertView textFieldAtIndex:0] text] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust

NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);

You probably want to use a network library like AFNetworking, and save yourself some time :)
